US Patent 7891291 Double lift tank wine press

A wine making apparatus includes an engaging mechanism for engaging a fermentation tank, and a press mechanism for pressing the wine making ingredients in the tank against an inner surface of the tank. In a described embodiment a tank has a pair of forklift attachment points and a movable platform on a wine press mechanism is adapted for receiving the forklift attachment points. A lifting apparatus raises the platform and tank such that the contents of the tank are crushed by a relatively fixed plate above the tank. A pair of hydraulic rams are connected in series such that fluid output from one raises the other, thereby assuring that the platform and tank are evenly raised.
